revert(ci): undo AOTI .pt2 compile / GPU test overlap (#5882)

[njzjz-bot]

Reverts #5882 — "ci(cuda): overlap AOTI .pt2 compiles with GPU unit tests".

This undoes the CUDA CI orchestration that PR added:

• The two-lane pytest split in test_python (-m aoti_compile vs -m "not aoti_compile").
• The aoti_compile pytest marker machinery in source/tests/conftest.py (producer list, pytest_collection_modifyitems tagging, and the runtime drift guard).
• The aoti_compile marker registration in pyproject.toml.
• The persistent AOTInductor compile cache (actions/cache) in both CUDA jobs.
• The per-lane JUnit report upload.
• The phase-gating (DP_CC_SKIP_BUILD / DP_CC_SKIP_CTEST) and atomic .so install changes in source/install/test_cc_local.sh.

The serial python -m pytest source/tests invocation and the original test_cc_local.sh flow are restored.

Conflict resolution

#5882 was followed by unrelated commits that touched the same regions. The revert preserves those later changes and only undoes #5882:

• Dependabot bumps preserved: actions/setup-python@v7 (chore(deps): bump actions/setup-python from 6 to 7 #5898) and actions/upload-artifact@v7 (chore(deps): bump actions/upload-artifact from 4 to 7 #5900) are kept. Only #5882's additions (the actions/cache blocks and the JUnit upload step) are removed; the version bumps that landed in the same context stay.
• DPA4 test fixtures preserved (feat(dpa4): DPA4/SeZM on the NeighborGraph lower — graph-native port, multi-rank, native spin, charge-spin/bridging #5884): the native-spin / bridging fixture generators gen_dpa4_spin.py, gen_dpa4_zbl.py, gen_dpa4_spin_chgspin.py, and gen_dpa4_spin_zbl.py are kept in test_cc_local.sh (re-indented to the restored single-lane flow). The matching entry #5884 added to _AOTI_COMPILE_MODULES is dropped together with that set, since the whole aoti_compile partition feature is being removed — the test_zbl_bridging module still runs, just unpartitioned.
• Unrelated docs dependency bumps in pyproject.toml (sphinx / myst) are untouched.

Net result: conftest.py matches its pre-#5882 state exactly; test_cuda.yml differs from pre-#5882 only by the preserved setup-python@v7 bumps; test_cc_local.sh differs only by the preserved DPA4 fixtures; pyproject.toml differs only by the preserved docs dependency bumps.

📝 Walkthrough

Walkthrough

The pull request simplifies CUDA Python CI to one pytest run, removes the shared AOTInductor cache and marker declaration, adjusts conditional framework imports, and makes local C++ build, fixture generation, and ctest execution unconditional.

Changes

CI test execution

Layer / File(s)	Summary
CUDA Python test configuration and execution .github/workflows/test_cuda.yml, pyproject.toml, source/tests/conftest.py	The CUDA workflow removes the AOTInductor cache and split pytest lanes, runs python -m pytest source/tests once, recognizes only the run marker, and imports Paddle and TensorFlow earlier when configured.
Local C++ build and test flow source/install/test_cc_local.sh	The script removes build and ctest skip gates, performs direct CMake configure/build/install steps, copies the PyTorch custom operation directly, preserves parallel fixture generation, and always runs ctest.

43-57: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Non-atomic overwrite of an already-loaded .so.

shutil.copy2 truncates and rewrites dst in place. If SHARED_LIB_DIR/libdeepmd_op_pt.so is already mapped by another process (or a rerun on a dirty runner), the overwrite can fail or leave a torn library. Copy to a temp file in the same directory and os.replace it, which is atomic and leaves existing mappings intact.
